This small, incomplete review holds no real spoilers.

Jennifer Lawrence turned up the acting switch a notch. Might be her best performance till date overshadowing 'winter's bone' while showing her great talent and potential of her becoming a movie superstar (if she isn't already bc of her internet popularity and looks.)

This part was more balanced as the last movie, and sets the emotional trigger on sharp for the finale next year.
Again a compliment to Elizabeth Banks who captures the role of Effie amazingly well. Even though she originally wasn't supposed to be on screen until the finale, the creators and writer Suzanne Collins decided to let her replace Plutarch's assistent so she could be in this movie, which was a wise decision imho to use a familiar face in stead of a unknown side character.
I was a bit disappointed about the lack of influence of Natalie Dormer, but we might have to wait for the last movie for that to happen.
Sidenote: It is harder to find a movie without Julianne Moore nowadays, than one with her lol.

There is a lot of conversation, the biggest part due to this being the politics part in the story. This is a big part of stories base after all, and is important in its message.
I really was surprised they used the 'Hanging tree' song in the movie, I kinda suspected they would skip it, and it was a great surprise and a good decision the didn't. It has a lot of importance for Katniss, since it depicts the struggle of the districts against the capitol, and her relationship with her family (mainly her dad) and later with Peeta.
Lawrence is definitely not a singer though, she doesn't have the voice for it hehe. Good thing they have computers nowadays.

Depending on how part 2 will turn out, I think they made a good choice in splitting the movie in two, even though it is probably done just for the cash and not for storytelling.
